Solar Hot Water



Switching from electric to solar hot water was one of the easiest and most effective ways we cut our energy bills and reduced our households greenhouse gas emissions. Electric hot water systems are the most common way household water is heated in Australia. Depending on the household, they can be responsible for anywhere between 25% to 60% of the households energy bill, and contribute a substantial amount of greenhouse gases.

We found a 300L Solarhart hot water system was best suited to our current and future needs. It’s a flat panel type, and the panel and tank sit on our north facing roof, to catch plenty of sun. It has an electric booster, but we’ve set it up so it only comes on when we manually flick the switch. We find in our sunny location we only need to turn on the booster on for about half an hour a handful of times a year.
